I have installed the batteries properly however the dancing cabbage patch doll doesn’t make a sound and doesn’t move.
Cabbage Patch Kids is a line of dolls created by Xavier Roberts in 1978. They were once the most sought after toy for Christmas during their peak popularity.
Clean the contacts and try again. If that doesn’t work, then there must be a loose wire inside or something.
I couldn’t find any specifics for getting to the electronics, but most guides to cleaning and restitching the dolls start with removing the zip-tie that holds the head on. You might find a point of ingress into the circuitry from there.

This video is poor quality, but shows someone getting inside of the snack time cabbage patch doll.
